Up to 90% if half dose followed by full

It's said. I suspect these very precise % figures might turn out to be a bit misleading - insufficient cases yet within the trials. But in any event, we don't 'need' a fully 100% effective vaccine do we? - although were we to have one that would be lovely no doubt - as long as most people who are vulnerable are protected then our health services can cope and although there will be some who develop it badly, there won't be many. Even 70% would probably achieve that?
